Comparing hammer drills to other types of drills
How Hammer Drills Stand Apart from Other Power Tools
When shopping for a cordless drill set, it's easy to get overwhelmed by the variety of drills and tools available. Hammer drills, standard drills, and impact drivers each have their own strengths, but understanding their differences helps you choose the right tool for the job.- Hammer Drills vs. Standard Drills: The main difference is the hammering action. While a standard drill rotates the drill bit to create holes in wood or metal, a hammer drill adds a rapid, percussive motion. This rotary and hammering action allows the drill to break through hard materials like masonry or concrete. If you need to drill holes in brick or stone, a hammer drill is the better choice. Standard drills are more suited for lighter tasks, such as drilling in wood or driving screws.
- Hammer Drills vs. Impact Drivers: Impact drivers are designed for driving screws and bolts with high torque. They use a different kind of impact mechanism, which delivers rotational force rather than the forward hammering action of a hammer drill. While impact drivers excel at driving long screws into tough materials, they are not ideal for drilling holes in masonry. Hammer drills, on the other hand, are built for drilling into hard materials, thanks to their combined rotary and hammering action.
- Hammer Drills vs. Rotary Drills: Rotary drills, sometimes called rotary hammers, are heavy duty tools used for larger masonry jobs. They offer even more powerful hammering action than standard hammer drills and are typically used for drilling larger holes in concrete. For most home or shop projects, a cordless hammer drill provides enough power and versatility without the bulk of a rotary drill.
